Fiber optic datasets, collected using existing telecommunications and science cables, provide first-of-kind recordings of earthquakes, ocean/solid-earth interactions, hydrodynamic phenomena, and marine mammals. The Spring Webinar will highlight some of the latest work in this space, and present new open access datasets for the general science community to dive into this emerging field for themselves. Please see the attached flyer for more information about the speakers. This event will be held in Zoom Webinar format and will feature the following presentations along with time for Q&A. A recording will be made available on YouTube after the event. - L?a Bouffaut (Cornell University) - DAS4Whales: A Case-Study of Baleen Whale Monitoring using Distributed Acoustic Sensing - Ethan Williams (CalTech) and *William Wilcock *(University of Washington) - A Community Test of DAS and DTS on the Ocean Observatories Initiative Regional Cabled Array - Han Xiao (University of California, Santa Barbara) - The Moving Sources of High-Frequency Microseisms - Pierre Martz (Infinera Corp.) - Seismic Detection and Localization using Submarine Cables - Mikael Mazur (Nokia Bell Labs) - Environmental Sensing using Coherent Optical Transceivers Use of Distributed Acoustic Sensing is rapidly expanding in our community, prompting the initiation of an Distributed Acoustic Sensing Research Coordination Network to facilitate workshops, tutorials, and other opportunities for sharing ideas and resources. This webinar is one in a planned series on different topics within Distributed Acoustic Sensing.
